8x + 5x + 9 = 61
Collect 'like' terms.
13x + 9 = 61
Subtract '9' from both sides
13x = 52
Divide both sides by '13'
x = 52/13
x = 4

8x = 5x+24 8x-5x = 24 3x = 24 x = 8
5x+49 = 8x+13 49-13 = 8x-5x 36 = 3x x = 12
first get the left hand side to only contain x's this requires you to get rid of the 9 on the left hand side so minus 9 on both sides of the equal sign so 8x + 5x + 9 = 61 becomes 8x + 5x +9 -9 = 61 -9 which is 8x + 5x = 52 now add the x's so 13x = 52 then divide both sides by 13 to find the value of x x = 4

5X+6=8X move 5x to the other side 6=8X-5X 6=3X then solve for x 6/3 = X 2 = X so X = 2 is the answer
